Measuring a coil diameter

Tonight’s Post is in some ways almost an embarrassment to admit. I have finally purchased a digital calliper and have found it to be one of the most useful tools I have ever purchased. Before going into details about that I have a few announcements to make about this website

Circles and Cycles

Header

Sine and Cosine.

I created a video over the weekend showing the relationship of a sine wave to a cosine wave. The cosine wave is shifted 90 degrees from a sine wave. (Think Capacitors and Inductors!!! Deja Vu all over again!!!)

First, I create the two waveforms using the unit circle method and CAD.

Short term energy storage, time delays, and oscillations.

We are quickly getting toward the end of our talk the theory of the thermistor circuit and will soon move that into construction. While construction is interesting, it is tough to create frequent posts of interesting content, so we are very soon going to move into some energy storage components. In electricity those are inductors

How a beam resists bending. (Moment of Inertia)

Rubber Band simulation of a beam subjected to bending.

In the post “Stress, Strain and finding center“, I talked about simple compression and tension and how beam or column elongates under tension and shrinks under compression. In the elastic portion of the stress strain curve the beam is acting like a very very strong

Episode 7 – Simple Machines Part 2

This episode is a continuation of the previous episode. In this one we continue to explore the force and distance relationship with three new simple machines: the pulley, the wheel and axle, and the screw.

II also want to take this time to introduce a facebook page for this blog. The facebook page is: Create

Episode 6 – Simple Machines Part 1

In this episode we will discuss simple machines and the concept trading distance for force to get the same work completed. Work is defined in physics as Force X Distance. Often it is advantageous to use less force over a greater distance to accomplish work that could not be done otherwise. Simple machines are designed
